SPECIFICATION forming part of Letters Patent No. 347,136, dated August10, 1886.

Application filed February 24, 1886. Serial No. 193,021. (No model.)

To all whom it may concern..-

Be it known that I, WILLIAM E. TALLOO'I, of Groton Landing, in thecounty of \Vestchester and State of New York, have invented a new anduseful Improvement in Brick-Machines, of which the following is a full,clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the'figures.

Figure 1 is a side elevation of my improved brick-machine. vation of thesame. Fig. 3 is a sectional front elevation of themold-table and themold-driving frame, taken through the line as m, Fig. 2. Fig. 4 is abottom view of the same, parts bethe mud-cylinder and the wipers, thevertical shaft being shown in section. Fig. 6 is a side elevation,partly in section, of a part of the vertical shaft, and showing theguard-collar in section.

The object of this invention is to improve the construction of thebrick-machines for which Letters Patent No. 237 ,636 were issuedFebruary 8, 1881,Willian1 E. Tallcot, inventor, in such a manner as tomake them more convenient in use and more reliable in operation.

The invention consists in the constructionand combination of variousparts'of the machine, as will be hereinafter fully described.

A represents the base-frame of the machine, the upper forward part ofwhich projects and has a platform, 13, attached to its top, to form atable to receive the molds and support them while being filled.

To the top of the rear part of the frame A is attached thesemi-cylindrical base 0, to which is attached the lower end of themud-cylinder D. To the opposite sides of the upper end of themud-cylinder D are attached the ends of an arched cross-bar, E, in thecenter of which is formed a bearing to receive the upper end of theverticalshaft F, or 'a journal formed upon the said upper end. The upperend of the journal of the shaft F is covered 'with a cap, G, to preventmud from getting into the bearing and wearingthe said bearing andtheshaft-journal.

The lower part of the shaft F revolves in a bearing, H, secured to thebase 0, and which Fig. 2 is a sectional side elefreely into thelowerpartof the said cylinder.

To the shaft F just above the collar J are attached or upon itarejournaled dovetailed ribs L, which fit into dovetailed grooves M inthe shoes M, so as to connect the said shoes securely to the said shaft.The outer surfaces of the shoes M are curved, and to them are secured bybolts N the curved wings or wiper plates 0 by which the mud is pushedthrough an opening, P, in the lower part of the forward side of thecylinder D into the press-box Q secured to the forward side of the saidcylinder. By this construction the wipers will be independent of eachother and can be readily detached from the shaft, and thewiper-platescan be readily detached from their shoes and replaced with new plates.If desired, the wiper-plates and their shoes can be made in one piece;but I prefer the construction first described, as it allows thewiper-plates to be made of steel and their shoes of cast-iron or steel.In the bottom of the press-box Q is formed an opening, through which themud is forced down into the molds by the plunger It. The plunger It,upon its ends and forward side, is provided with a packing, 2, the upperand lower edges of which are beveled, and which is held out against theinner surface of the press-box Q by spiral springs 3,placed in recessesin the said plunger, and which is designed to prevent the mud fromworking up between the said plunger and the ends and side of the saidpress-box. Upon the upper side of the end parts of the plunger R areformed keepers S, through which is passed a bar, T. The bar T passesthrough vertical slots in the upper parts of the ends of the press-boxQ, and to the ends of the said bar T are pivoted, by pins or other suitable means, the forked upper ends of the connecting-bars U. The lowerends of the connecting-bars U are pivoted to the forward ends of thearms V, the rear ends of which are secured to a shaft, \V. The shaft XVrocks in hearings in the base-frame A, and to one of its ends is securedat its angle the three-armed lever X. The upper arm of the three-armedlever X is made short, is slotted, and to it is pivoted the lever Y. Tothe rear ends of the levers X Y are pivoted rollers Z, which are strucksuccessively by the cam a, secured to the drive-shaft b. The drive-shaftb revolves in hearings in the base-frame A, and power can be applied toit by a pulley and belt, or other suitable means. \Vith thisconstruction, as the cam a strikes the roller Z of the lever Y, thelevers X Y and the arms V will be vibrated to drawihe plunger R downwardand force the mud out of the press-box Q, and into the molds. As the cama strikes the roller Z of the lever X, the levers Y X and the arms Vwill be vibrated to force the plunger 1 upward, to allow more mud toenter the pressbox Q.

To the forward end of the levcrX is pivoted the lower end of the bar 0,in the forward edge of which are formed rceessesd, to receive the lag 0,formed upon or attached to the side of the forward end of the lever Y,so that by adjusting the catch-bar c, to change the lug c from one toanother of the recesses d, the rear ends of the lovers X Y will beadjusted at a greater or less distance apart, to give a less or greatervibration to the levers X Y and the arms Y, and a less or greatermovement to the plunger 2, as may be required.

The upper end of the catch-bar c is extended forward, as shown in Fig.1, so that it can be conveniently reached and operated by the attendantstanding in front of the machine. The lower end of the catch-bar c isextended a little below its pivot, and. has teethf formed upon it, withwhich engages a spring-pawl, g, secured to the lever X, to hold thecatch-bar c in gear with the lever Y when the machine is at work.

To the drive-shaft Z: is attached alarge beveled gear-wheel, h, theteeth of which mesh into the teeth of the large beveled gear-wheel t,attached to the lower end of the vertical shaft 1 so that the saidvertical shalt will be revolved from the said drive-shaft.

j is a frame, which is placed just below the platform I, and the sideedges of which slide in grooves in the inner sides of the side top barsof the frame A. To theupper side of the rear end of the sliding frame jare attached the rear ends of two bars, 7.1, which are made with anupward curve or offset, I, at or near their rear ends, to raise the saidbars above the level of the platform I The bars 7; pass through holes inthe front wall of the semi cylindrical base (1, and to their forwardends is attached a cross-bar, 111, so that the mold will, be pushedsquarely beneath the press-box by the forward movement of the said bars7:. Upon the forward side of the cross-bar m, near one end, is formed,or to it is attached, a lug,

a, to serve as a stop to the mold when being pushed into place beforethe said cross-bar. \Vith this construction the part of the front wallof the base 0 below the push-bars 7.: will prevent the sand falling uponthe platform or table 15 from falling from the rear end of. the saidplatform, and coming in contact with and wearing the bearings of thesliding frame.

The sliding framej is pushed forward and back by the cams 0 1), attachedto the vertical shaft F just above the gear-wheel The cam p operatesagainst the downwardly-projecting flange q, attached to the rear end ofthe frame j, to force the said frame back.

To force the sliding frame j forward. the cam 0 operates against theroller 0-, pivoted to the rear end of the bar or interior frame, 8,which slides in a way in the forward middle part of the said framej. Theforward end of the bar a, when the said bar is in position for theroller 0' to be operated upon by the cam o, rests against a shoulder, t,formed upon the rear end of the lover a, the said rear end of which ispivoted to snpportso, attached to the sliding framej. The forward end ofthelever a is provided with a catch, 10, to engage with a spring-latch,41?, attached to the forward part of the frame], and which is made ofsufficient strength to hold the said lever it against the forward pushof the sliding bar a under ordinary circumstances; but should the moldin its forward movement encounter a stone or other obstruction thespring-latch a will yield and allow the catch-lever u to drop andwithdraw the shoulder from the end of the sliding bar s, so that thesaid sliding bar moves forward, carrying the roller 1- out of reach ofthe cam 0, and therefore the sliding frame j and the push-bars 7.: willnot be operated by the revolution of the shaft F and its cams o p. Thecatch-lever u is also provided with a handle, y for convenience inraising it into engagement with the spring-latch :0, and with a stop, a,to strike against the framej, andlimit the upward movement of the saidcatcli lever.

\Vhen the obstruction has been removed the sliding bar 5 is pushed backinto such a position that the catch-lever a can be raised intoengagement with the spring-latch m by means of a rod, Z, attached to theforward end of the sliding bar 8, and projecting into such a positionthat it can be readily reached and operated by an attendant standing infront of the machine.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a brick-mac]1ine,the combination,withthe drive-shaft I), the rock-shaft \V, the plunger R, and the bars U andarms Y, connecting the said rock-shaft and plunger, of the cam (t,attached to the drive-shaft, and the levers XY, provided with rollers Zat their rear ends, and connected with each other and the rockshaft,substantially as herein shown and described.
